Amid the marches, rallies and Facebook posts, a common theme emerged: To effect change, people must engage in the political process. Protests are one tool — but actually contacting elected representatives is key.

So who you gonna call?

For folks engaging in their first form of activism — anyone, really — knowing how to reach your legislators is not always easy. (That was true during America’s previous protest movement too: the Tea Party.)

The website is a 1-stop shop to help citizens contact their senators and representatives. It offers a range of issues — healthcare, climate change, education, women’s rights, immigration, civil rights, the Supreme court, constitutional crisis — to weigh in on.

And it provides a sample call script, for users who can’t find the right words to convey their disappointment/distrust/dismay at the latest news.

YouLobby is the brainchild of Aaron Eisman and Kira Ganga Kieffer. Both are Staples High School 2004 alums; both graduated from Brown University 4 years later.

They took very different paths to their current project.

At Staples, the 3-year Authentic Science Research course (and mentor Dr. A.J. Scheetz) sparked Aaron’s curiosity. He also served as yearbook editor.

At Brown he concentrated in applied math, with a focus in economics. He did biochemistry research at Yale for 2 summers.

After college he worked for 5 years as director of technology at an asset management firm,where he taught himself to code, and manage online data and cloud computing.

Then he made a career change, into medicine. Two years working as a research coordinator at Massachusetts General Hospital reawakened his passion for science research, which he continues to do at Brown’s Alpert School of Medicine. He’s in his 2nd year — while also doing research in biomedical informatics. The aim is to use healthcare data to improve clinical outcomes.

Kira was a 4-year writer (and senior co-editor-in-chief) for Inklings, the Staples newspaper. Steve Rexford encouraged her to do investigative reporting, and break stories that might be unpopular with administrators. She co-founded an after-school reading club for girls at Beardsley Elementary School in Bridgeport, and worked for United Way — early experiences in social outreach and community engagement.

A history and religious studies concentrator at Brown, she became passionate about studying evangelicalism and politics. She examines those very timely topics now, as part of Boston University’s doctoral program. In between, she spent 6 years in corporate marketing.

Oh, yeah: Aaron and Kira dated as Staples seniors. They’ve been together for almost 13 years — and got married in 2015.

Over the past few months, politics was all they talked about. They grew increasingly concerned about the health of American democracy; threats to women’s, LGBT and civil rights; the need for universal healthcare; the denial of climate change; the importance of environmental protection and industry regulation; immigration and refugee crises; racial and religious intolerance — you know, all those minor issues.

After the election, the couple began calling their representatives. They attended the women’s march on Washington. It was their first protest, and they were hooked.

“We decided these causes are worth fighting for,” Kira says. “We needed to work to make our country work better, and treat all people witih respect.”

While struck by the massive crowds of diverse people, all standing in solidarity, Aaron and Kira worried that grassroots energy might fizzle out. Driving back to Massachusetts, they talked about the importance of engaging their representatives.

They decided to make a tool to help. They came up with the “YouLobby” name, and when they got home they bought the domain name. Aaron put his coding skills to work. Kira did the same with her marketing talents.

Kira’s mother gave important feedback: She said the daily script made it easy to call.

Two weeks later, they launched.

The website is simple. Other sites do similar things, but without the ease of use, visual appeal and social media presence of YouLobby. A Facebook page sends out daily updates, and the pair use the hashtag #EveryCallCounts on Twitter and Instagram.

Aaron and Kira’s site also offers important bullet-point facts and arguments, and a homepage “Issue of the Day.”

Reaction was overwhelmingly positive — and instant. Within 24 hours, users from 29 states were calling their representatives. Over 500 zip codes have already been entered.

These days, Congress is inundated with phone calls. Citizens turn up in record numbers at town halls and constituent meetings. YouLobby is doing what it can to keep the pressure on.

Democracy is not a spectator sport. And no one knows that better than Kira’s mother.

She had never called a representative in her life. Using YouLobby, she now calls every day.
